Andy, nice drawing of your LF-MF antenna setup! What are the values of the caps and coils in your two L-C matching/tuning devices? I'm interested in the ones for 500 kHz., as I might try something similar on my antenna that I use on my BCB xtal radios. 73, J.B., VE3EAR LowFER Beacon "EAR" 188.830 kHz. QRSS30 EN93dr
